Does the name of sitemap index file matter?

I am going to be submitting a new sitemap index file to yandex, yahoo, bing, ask and google. Due to technical issues I can't call the index sitemap.xml Does it matter at all to engines if its called something like sitemap2.xml or sitemapindex.xml?

the sitemap index will contain links to a few large xml.gz files that contain the actual site urls.

Thanks

 

Call them what you want.

mapindex.html, sitemapindex.html sitemap-index.html smi.html or whatever

 

thanks

i was suspecting that much, but wanted to make sure...

 

What ever you decide to call it, be sure and log into google Webmaster Tools and point them toward the file.

 

thank you.

 

What do you think about Geo xml sitemap?

 

Also, use the Robot.txt file for SE that do not support Google Webmaster Tools, like the rest. See http://www.catanich.com/sitemaps-via-robots-txt.asp for example on how to set this up.

 

Thanks.
I named it sitemaps-index.xml and added the robots text. Thank you everyone.

 

Was that question to me or...?

 

No difference for me... i just installed it and forgot them forever
